High Quality Slurry Pump was Delivered to Dongying for Building Yellow River Beach Area

High quality slurry pump, also known as sand pump and sediment pump, is an impurity pump that extracts the medium such as mud, fine sand, tailing slag and transports them over long distances. The Ocean brand high quality slurry pump is precisely cast with high wear resistant alloy material. High quality slurry pump is suitable for marine suction, sand pumping, reclamation, construction of docks,  , metallurgical transportation of tailing, river dredging and other industries, and it can also be used in electric power plant, etc.

Selection Procession of High Quality Slurry Pump

One customer from Dongying was using a DS 250-75 slurry pump produced by other supplier, supporting 250 KW motor. Inlet diameter of the  slurry pump is 10 inch / 250 mm, outlet diameter is 8 inch / 200 mm, discharge distance for 5 km. In the using period, the customer found that the slurry pump impeller wore quickly and had many cracks. It was also leaking and could not be used anymore.
On December 23, 2018, the customer contacted our company. Through communication, we found that the slurry pump type labeling parameters were incorrect. The actual parameters of the slurry pump type are much smaller than the marked parameters (Flow capacity is 1100 m³/h , Pump head is 50 m), there are problems in processing and assembly accuracy, especially there is no dynamic balance on impeller, this causes the impeller and the rear guard are easily attached together, which exacerbates the friction and the damage is relatively fast.
At that time, it was winter and the temperature was below zero, stopping the pump for a long time would cause the pipeline to freeze, this led to damage easily and reduced the service life of the pipeline. Our engineers suggested the customer reducing the frequency first in order to reduce the speed of the sand pump. The slurry pump only pumped water to ensure that the water in the pipe flowed. On the other hand, the assembly workshop of OCEAN Pump immediately assembled a 12-inch high quality slurry pump (DS 300-75) and the supporting base. Because the sand pump machine belongs to double pump casing series, it requires pressure and water leakage test. The test ensures that the inner pump casing, the front and rear guard plates are well sealed and leak-free. After overtime work, the commissioning was completed at 10:00 pm on December 23, 2018. The high quality slurry pump would arrive at the construction site at 8:00 on the 24th.

On-site Installation and Commissioning for High Quality Slurry Pump

Our sales manager and after-sales installation engineers drove to the customer’s working  ite at 3 am on December 24, 2018, arrived at the site at 7:30, and started to install the sand pump.

1. Stop the high quality slurry pump and booster sand pump on board and discharge the water in the pipeline.
2. Temporarily raise the inlet pipe and the discharge pipe of the booster sand pump to ensure no water flow and save drainage time.
3. Remove the original slurry pump DS 250-75, and hoist the original 250 KW motor to the 12 inch high quality slurry pump installation base of our company, and start to adjust the concentration of the motor and mud pump and fix it.
4. Because the original pump type inlet is 250 mm and the outlet is 200 mm, and the new high quality slurry pump type inlet is 300 mm and the outlet is 250 mm. The imported and exported reducer tube is installed at the original pipeline.
5. Install a new high quality slurry pump DS 300-75 as a whole, and debug the steering and connecting pipes. The customer’s previous slurry pump does not have an outlet vent valve installed. According to the site conditions, an exhaust valve is installed to facilitate air removal and reduce Cavitation of the slurry pump.
6. Start the high quality slurry pump and booster sand pump for discharging on the dredger respectively, and adjust the power frequency of the booster sand pump according to the outlet flow to achieve the best relay condition.The whole modification process was very smooth. The customer thanked our company for actively cooperating, avoided further losses such as freezing on the pipeline, and learned the matters needing to pay attention to the high quality slurry pump through the modification process. The customer lamented that it is necessary to look for the brand when purchasing the slurry pump. Look for the manufacturers, remember that the price is low, find some personal pump companies.
